[0002] A crystal resonator is an electronic component that utilizes the piezoelectric effect and is widely used to generate precise frequency signals. Its basic structure includes a resonator and electrodes made of crystal material. The working principle is that when an external voltage is applied to the crystal, the crystal will produce mechanical vibrations, thereby generating a stable electrical signal. The oscillation frequency of the crystal resonator depends on its shape, size and material properties. It usually has high frequency stability and low phase noise. The main applications of crystal resonators include clock circuits, frequency synthesizers and signal processing.

[0032] The anti-detachment component includes two pins 3, the left end of the pin 3 is fixedly connected to the inside of the resonator body 1, a plurality of grooves 4 are provided on the outside of the pin 3, and a plurality of barbs 5 are provided on the outside of the pin 3. The pin 3 is used to pass through the circuit board and be fixed on the circuit board. The groove 4 is used to increase the contact area with the solder, and the barb 5 is used to wrap the solder to avoid cold soldering. The grooves 4 are equidistantly distributed in a straight line, and the barbs 5 are equidistantly distributed in concentric circles. The pins 3 are symmetrically distributed, and fixation is achieved by cooperating between the grooves 4 and the barbs 5 on the pins 3.

[0033] Reference Figure 1 - Figure 3 The sealing component includes a base 2, the left side of the base 2 is fixedly connected to the right side of the resonator body 1, and paraffin 6 is provided on the right side of the base 2. The outer pin 3 is sleeved inside the base 2. The base 2 is used to connect the resonator body 1 to facilitate fixation with the circuit board. The paraffin 6 is used to keep the internal space of the base 2 stable. The paraffin 6 is in a closed ring shape. The melting point of the paraffin 6 is 58°.
